Y axis and X axis
« on: October 07, 2019, 09:52:27 PM »
God morning and hello.
Is it just me that have the Y and X axis going wrong?
Attach a pick of a machine to get better explaining.
When the laser head is going to you if you stand in front of the machine like in pic, I have to use axis Y. And if I love the head left or right I have to use axis X.

Don't know why this is, I know I can change that Y left is pressing Y right on my computer.
But if the the head goes to me in front that is -X and so on.

Yup that's how they work. 0,0 is the bottom left in your picture. Y is back and forth and x is left and right.

Well than I have to learn it goes that way, my laser, water and plasma cutters at work have X as back and forth. Starting point when cutting, at right bottom  😊
Thank you for the answer.

I have been dabbling in Marlin firmware for 3D printers so GRBL homing options are a little fuzzy.

1. GRBL is a bare bone gcode interperter designed to fit in a Atmel 328 CPU.
2. The difference between HOME and LIMIT switches can be confusing.
3.  When I first used my core-xy fixture the HOME position was the upper right and was corrected to lower left via the parameters.
4.  The source code for GRBL firmware is readily available. Read the comments around line 135. You may be able to configure per your expectations.
5. The difference between "lower left" and "upper right" can be reversed by rotating the machine 180 degrees.
